A population of sh is living in an environment with limited resources in such a way that the population (measured in thousands of sh) at time t (measured in years after 2013) is given by P(t). (a) In a sentence or two, explain the physical interpretation of P' (1) (b) Suppose the graph of P (t) is shown below. y=P(t) Use the graph provided to make a rough sketch of the graph of P'(t). (c) Based on your graph, at (approximately) what time will the population be growing the fastest
